PV Vehicle-Mounted Systems

This system uses solar panels installed on the vehicle body (such as the roof) to charge the vehicle's batteries. It provides power for:
- Starting battery to prevent no-start issues due to low charge.
- Storage battery for appliances like air conditioners and refrigerators when parked.
- On-board devices like air conditioning to reduce fuel consumption.
- New energy vehicle batteries to extend driving range.
Suitable for vehicles such as vans and campers.

The system requires customized configuration with flexible parameters based on specific application requirements.

product details

King Kong Pro Series Solar Panels

Grade A high-efficiency monocrystalline silicon

laminated solar panel

Patent Number : ZL 2024 2 0137117.3

The King Kong PRO solar panels adopts an original distributed diode technology. Under the same shading conditions, it has the advantage of higher output power compared to common modules. It is encapsulated with 3.2mm ultra-white tempered glass and protected by an aluminium alloy frame. There are screw holes for installation on the frame, which can be used for planar installation.

Solar Charge Controller

Patent number：ZL 2018 2 1299429.5

MPPT maximum power tracking module

The MPPT solar controller is used to control the PV panel for battery charge. The built-in MPPT maximum power tracking module can detect the solar panel's power generation voltage in real time, and track the highest voltage and current value (VI), so that the system can charge the battery with the maximum power output. It is applied to the solar PV system, which coordinates the work of solar panels, batteries, and loads, and has the function of protecting the battery from overcharging and over discharging.

Features

✔ Advanced dual-peak or multi-peak tracking technology, when the panel is shaded or part of the panel is damaged, the I-V curve will come into being multiple peaks, and the controller can still accurately track the max power point.

✔ Built-in maximum power tracking algorithm, which is about 20% higher than the traditional PWM charging efficiency, can significantly improve the energy utilization efficiency of PV systems.

✔ Up to 99.9% MPPT tracking rate.

✔ Supporting gel batteries, sealed batteries, open batteries, lithium batteries,etc.

✔ Current-limit charging mode. When the power of the panel is overload and the charging current is greater than the rated current, the controller automatically reduces the charging power to operate it at the rated charging current.

✔ Support battery voltage automatic identification.

✔ LED fault indication, LCD abnormal information indication, convenient for the user to determine the system fault.

✔ LCD screen shows device running data and status, and supports controller parameter altering.

✔ Standard MODEBUS protocol to meet the communication needs on different occasions.

✔ External Bluetooth, mobile phone app connection, to view solar charging and battery storage in real time.
